Abstract
Blade arrangement for a hair clipper comprising a comb with an anterior edge, which contains tooth elements; a blade with an anterior cutting edge, which contains tooth elements, wherein the cutting edge at its anterior end is downwardly sloped towards the lower cutting edge, and wherein the blade is configured to be movable relative to the comb; a connecting device, which connects the comb and the blade relatively movable to each other; and a pretension element, which preloads the comb and the blade against each other characterized in, that the cutting edge of the blade have a wave shape, wherein the anterior cutting edge of the blade contains at least three tooth elements and/or the edges of each tooth element have a curved shape according to the wave shape.
Claims18
A blade arrangement for a hair clipper, comprising:
- a comb with an anterior edge, which is configured with comb tooth elements;
- a moving blade with an anterior cutting edge, which is configured with moving blade tooth elements extending in a forward-backward direction, wherein said anterior cutting edge is downwardly sloped at its anterior end towards a lower cutting edge, and wherein the moving blade is configured to be movable relative to the comb;
- a connecting device, which connects the comb and the blade movably relative to each other;
- and
- a pretension element, which preloads the comb and the blade towards one another, wherein said anterior cutting edge of the moving blade is construed in a wave shape extending in a direction lateral to the forward-backward direction of said moving blade tooth elements and configured to have a wave tip and a wave valley, the edges of the individual moving blade tooth elements are curved in said lateral direction so that said edges define the wave shape,
- wherein said moving blade comprises at least three moving blade tooth elements with different lengths,
- wherein each wave of said wave shape extends at least across four moving blade tooth elements, wherein each wave of said wave shape extends from one longest moving blade tooth element to another longest moving blade tooth element, and
- wherein said moving blade comprises at least two moving blade tooth elements with different curvature in said lateral direction according to said wave shape.
